Hello and welcome back to the Project SR E30 series! In this episode, we will be addressing the last few issues holding us back from finally installing the engine once and for all.
You may recall that previously, we got a brake booster that fit with the SR, but we never actually made the brake booster function. Today, we will modify that brake booster to work, as well as address some exhaust clearance issues. We will also perform the final preparations to the SR before installation.
First things first, since this car is going to be a street car, we’re putting the heater lines back in. Funnily enough, the heater core inlet on E30’s is on the drivers side of the car, just like JDM S13’s. We can just use the cross-over style heater hoses that come installed on your SR when you get it from Japan.
We also scored an ACT Lightweight flywheel on craigslist for $20!!! It was in pretty rough shape, but nothing a quick trip to the machine shop can’t fix.
You might remember from part 1 that we had to use a very special tubular unequal length manifold in order to clear the brake master cylinder. Well, before installing the engine, we decided to redo the heat wrap on it. We cut off the old heat wrap and….

Love this series, great read and excellent photographs!
Hey just a heads up: when using a bolt and nut with Nord-Lock washers, you require a Nord-Lock washer on the bolt and the nut. There was a video posted up by the Nord-Lock group explaining how and when to use their washers. Looks like you only have one on the nut.
Wow, good catch! You’re absolutely right. We need to fix that.
Are there any special considerations for using a brake booster from and NA on a turbo car? I’m finding very little information on this topic. I’m installing a B210 brake booster on my 4G63 turbo swapped Datsun 510. Although this booster swap seems common in the 510 world, very few people have information to share about making it “turbo safe”.
There is no difference between a turbo and non-turbo brake booster as far as I understand it.
As long as there’s a check valve to prevent boost from entering, you’re fine.
really nice work guys!! Techline coatings makes a really effective coating for manifolds.. The effect is two fold. You’ll get about 100 degree drop in temp off the surface of the manifold and increase velocity of gases and aid throttle response. Also, the gold isn’t very effective. The silver heat reduction material :DEI heat shielding….is much more effective. So you would coat all you manifolds, Turbo housing (hot side) and if you want to get fancy you would coat all the parts you want to keep cool in their thermal dispersant coatings to shed heat. There stuff really work.. I’ve used them .. No affiliation what so ever
Thanks for the advice, we will definitely look into that. Currently we were planning on using DEI’s Form-a-Shield thermal barrier to help protect the brake master.
After all air is a great insulator and the DEI shield integrates air into its physical shape
